When you need to save storage space, you can create a virtual disk in thin provisioned format. The thin provisioned virtual disk starts small and grows as more disk space is required.

This procedure assumes that you are creating a typical or custom virtual machine using the New Virtual Machine wizard.


Launch the vSphere Client and log in to a vCenter Server system or an ESXi host.

You can create thin disks only on the datastores that support disk-level thin provisioning.


  • In the Create a Disk dialog box, select Thin Provision.


A virtual disk in thin format is created.

What to do next

If you created a virtual disk in the thin format, you can later inflate it to its full size.
